Male cicadas create loud buzzing noises by vibrating special membranes.

This sound is primarily used to attract female cicadas.

Distribution and Habitat

Global Presence

Cicadas are found on every continent except Antarctica.

They thrive in various habitats, including forests, grasslands, and urban areas.

Cicadas play vital roles in forest ecosystems.

Their emergence provides a sudden influx of food for birds, bats, and other predators.

Their abandoned exoskeletons become a source of nutrients for the soil.

Conclusion

Cicadas are fascinating creatures that contribute to the diversity and ecological balance of our planet.

Their unique appearance, sound production, and life cycles make them an integral part of the natural world.
